My name is David.
To access the alarm setup page you will need to manually assign an IP address to your computer, then connect to the adapter and change the IP address on the adapter to DHCP or a static IP address in the 192.168.1.x range, and then change the IP address on your computer back to the original DHCP or 192.168.1.x IP so that you can access the adapter.
To make the IP change on Windows 10 click the Start button, then the Search box and type ncpa.cpl in the Search box and press Enter.
In the Network Connections window that opens, right click on the network adapter you use to connect to the network and the IOGear device and click Properties, then click on TCP/IP v4 and click Properties. In the Properties window click Use the Following IP Address radio button and enter 192.168.254.5 and press tab then enter 255.255.255.0 for the Subnet Mask then click Apply then OK then OK again to save the settings. Then you should be able to connect to the IOGear adapter, change the IP address settings on the adapter to the 192.168.1.x range and then make sure the DHCP server on the IOGear adapter is disabled if you have a router on the network that is already supplying IP addresses via DHCP.
Please let me know the result and if you need further assistance. Also, please provide a
positive rating (3, 4, or 5 star) as that is how I receive credit for my work.
